AG-PB-1002.webp
RIPA Lysis & Extraction Buffer
Balanced ionic and non-ionic detergent buffer that solubilises cytoplasmic, membrane, and nuclear proteins in a single step while preserving immunoreactivity for downstream blotting.
AG-PB-2200.webp
BCA Protein Assay Kit
Colorimetric detection of total protein with high detergent tolerance and a broad working range. Includes BSA standards for a full standard curve.
AG-PB-3050.webp
ClarityECL Chemiluminescent Substrate
Enhanced luminol substrate for HRP-conjugated antibodies, delivering picogram sensitivity with a signal plateau long enough for multi-exposure imaging.
AG-PB-4310.webp
Prestained Protein Ladder, 10–250 kDa
Ten recombinant proteins covalently coupled to a chromophore, giving sharp bands for both molecular-weight sizing and visual confirmation of transfer efficiency.
AG-PB-5120.webp
Human IL-6 Sandwich ELISA Kit
Pre-coated 96-well strip plate with matched antibody pair, recombinant standard, and TMB substrate. Validated in serum, plasma, and cell culture supernatant.
AG-PB-6001.webp
Ni-NTA Agarose Affinity Resin
High-capacity nickel-charged agarose for purification of His-tagged recombinant proteins under native or denaturing conditions. Regenerable across multiple cycles.
